Frequency histogram of bovine skeletal muscle transcripts (blue circles). The overall distribution is bimodal (simulated by the red and yellow circles), and a relatively small number of highly abundant transcripts encoding muscle structural subunits, ribosomal proteins and mitochondrial proteins dominate. MSTN sits in the nexus between the two distributions, possessing an average abundance of ~7.
